Answer:
360 kilometres
Explanation:
To find the distance a car would have to cover if it has been traveling for four and a half hours, you can use the formula:
distance = speed x time
In this case,
distance = 80 km/hour x 4.5 hours
To calculate the distance in kilometers, we multiply the speed in kilometers per hour by the time in hours.
distance = 80 x 4.5
distance = 360 kilometers
So, the car would have to cover 360 kilometers if it has been traveling for four and a half hours at 80 km/hour.
